Application filed July 11, 1907. Serial No. 383,217.

To all whom it may concern:

Be it known that we, JOHN Rozmn and CHARLES W. GUTHRIE, citizens of the United States, residing at Sheridan, in the county of Sheridan, State of Wyoming, have invented certain new and useful Improvements in Railway-Ties; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in railway-ties, and more particularly to that class of ties which comprise a metallic shell or casing provided at its opposite ends with wooden blocks for su porting the rails and for receiving the rai securing means. Such ties, however, are open to the defect that the shell does not afford the necessary resiliency, owing to the fact that the over lapping edges of the metallic sheet from Which the shel'lis constructed are either rigidly connected together or are disposed at the under face or bottom of the shell, so that the weight of the rails will prevent the sepa ration of said edges.

It is the aim of this invention, therefore, to overcome such defect by forming registering slots in the overlapping edges of the shell,

and by disposing these edges at one or the other of the side faces of the shell, so that they will have a slight movement towards each other during the passage of a train over the rails mounted upon the ties, such movement being limited by the fastening-bolts which extend through the slots.

The invention will be readily understood from the following detailed description, and its preferred embodiment is illustrated in the accompanying drawings in which like parts are designated by corresponding reference numerals in the several views.

Of the said drawings, Figure 1 is a side elevation of a tie constructed in accordance with the present invention, Fig. 2 is a top plan view thereof, Fig. 3 is a transverse section through Fig. 2, Fig. 4 is an enlarged fragmental perspective view of the shell, showing its edges separated from each other, to illustrate the slots, Fig. 5 is a plan view of the tie with rails mounted thereon. Fig. 6 is a longitudinal section through Fig. 2.

Referring more particularly to the drawings, the numeral 7 indicates generally the shell or casing of the tie which is constructed of a single sheet of steel, bent so as to form a hollow cylinder or casing having open ends, the. opposite edges 8 of the metal being overlapped at one side of the tie as shown in Figs. 1 and 3. Each of said edges is provided with a series of vertical slots 9 which are disposed towards the opposite end of the tie, the slots in one edge registering with those in the other edge for the reception of the bolts 10 by means of which said edges are connected together.

The upper face of the shell is cut away adj acent the ends thereof to form apertures 11 of sufficient width to receive the base flanges 12 of a rail, each aperture having a recess 13 formed within its side walls, said recesses ex tending longitudinally of the tie, as shown. The tie is further provided at opposite ends with blocks 14 of wood or other suitable material which blocks are adapted to.be in serted longitudinally into the ends of the shell and under the apertures 11 through which the upper faces of the blocks are visible. These blocks form supports for the base flanges of the rails, said flanges being secured to the blocks by spikes 15 which are driven downward through the recesses 13 and into the blocks. It will thus be apparent that the casing or shell and the rail flanges protect the faces of the blocks from the weather, thus prolonging the life of the blocks to a material extent, and it will be likewise apparent that when the upper face of either block becomes worn or otherwise rendered unfit for use the block can be with: drawn from the casingor shell and'reversed and then reinserted.

The slots through which the fastening 'bolts extend have a length somewhat greater than the diameter of said bolts so that, upon the passage of a train over the track rails the slotted edges of the shell will move slightly towards each other, returning to their normal position when the train has passed thereover. Owing to this construction the tie becomes possessed of a resilience consider ably in excess of that present when the edges of the tie-shell are rigidly secured together or where the edges are overlapped at the bottom of the shell.

Displacement of the blocks within the shell is prevented by means of the spikes above-referred to, as will be apparent.

What is claimed, is,

A railway-tie comprising, in combination,

an open-ended shell constructed of a'single movement of said edges towards and from sheet of metal having its opposite edges each other.

overlapped at one of its sides, said overlap-, In testimony whereof, We affix our signaping edges being provided With registering tures, in presence of tWo Witnesses. 5 vertical slots; blocks removably seated I JOHN ROZINE Within the ends of the shell and adapted to receive rail-securing means; and a series of fastening-bolts passed through said slots to Witnesses:
